[igraph] Negative weights in betweenness centrality calculation

[Zhuojie Huang]

Hello,
I am wondering how the betweenness centrality calculation work on the
negative weights values. In our graph, we all have edges with negative
weights in which larger value means closer connections.

Thank you very much.
